3.7 Volt Rechargeable Battery 3500mAh NiMH Battery 2Pack Large Capacity Batteries for Headlamp, LED Flashlight, etc ZH

I have used two of these a while now and have had no problems. They last a good while and charge quickly.

Good

2 batteries ...not cheap but work OK......

Bought 4 of these batteries as replacement for existing 4 Efest 3500mAh batteries. Exceeded all expectations by far compared to the much expensive brands. Vaping for 2 full days with my Geekvape Legend 3 without needing to recharge. 100% charge held over 3 days so far. All four batteries performing great, happy days.

Seems good and holding charge well. Used in a battery carpet sweeper.

needed 2 new batteries for torch/flashlight. when inserted end-to-end in the torch the battery terminals cannot touch each other because the +ve terminal is too far recessed and the outer plastic wrapping prevents it from touching the -ve terminal of the other battery. they will probably work on their own but that is not what i needed and not what you would expect from any battery; they should be able to be connected together. I decided not to go ahead with a return as it wasn’t direct to Amazon and I’d have to pay. Without asking the seller contacted and issued a refund so I can’t fault their customer service. Thank you

Great seller!fast deliveryRecommended

Pure and utter crap, one never worked the other didn't charge
